Image segmentation method and device, electronic equipment and computer readable storage medium

Abstract

The invention provides an image segmentation method, which comprises the steps that first initial segmentation data and second initial segmentation data of a kidney image to be segmented are determined, and the threshold value of probability segmentation of the first initial segmentation data is greater than the threshold value of probability segmentation of the second initial segmentation data; based on the first initial segmentation data and the to-be-segmented kidney image, determining a growth prediction center line corresponding to the to-be-segmented kidney image by using directional growth operation; correcting the growth prediction center line to obtain a renal calyx and pelvis center line and a ureter center line; and based on the second initial segmentation data, the kidney calyx and pelvis center line, the ureter center line and the to-be-segmented kidney image, determining segmentation results for the kidney calyx, the pelvis and the ureter. According to the image segmentation method, the direction growth operation is utilized to carry out false connection on non-developing areas, breakpoints and missing are complemented, correction operation and subsequent processing are utilized, the segmentation accuracy is improved, and the problem of missing or breakage caused by non-developing of the image is solved.

Description

technical field [0001] The present application relates to the technical field of medical image processing, and in particular, to an image segmentation method and its device, electronic equipment and computer-readable storage medium. Background technique [0002] Accurate segmentation of renal calyces, renal pelvis and ureter can assist doctors in diagnosing and treating kidney diseases. However, due to factors such as the inability of the contrast agent to fully enter the renal calyce, renal pelvis and ureter, the complex situation of the abdomen, and the internal tissue lesions of the kidney, there is a problem that some areas are not developed in the acquired renal images, which leads to When segmenting with the ureter, there are missing or broken segments in the segmentation results. SUMMARY OF THE INVENTION [0003] In view of this, the embodiments of the present application provide an image segmentation method and device, electronic device and computer-readable stora...
